Dichotic Digits-Musiek Version

The Dichotic Digits test is an auditory processing disorder test for ages 7 and up using verbal stimuli. It is considered a dichotic test for binaural integration sensitive to brainstem, cortical, and corpus callosal lesions.

Dichotic Digits – Musiek version is a test by Dr. Frank Musiek. It is similar to the Dichotic Digits standard version.  That is, digits from one to ten are presented dichotically.  One set is single pair; the second is double pair.  Usually, the single pair set is for practice. Dichotic Digits-Musiek version includes the digit “seven.” In contrast, the standard version does not include the digit “seven” since it is a two syllable word in contrast to the other nine digits. The Dichotic Digits-Musiek version includes age-specific normative data on double digits for ages 7 and up. The standard version includes normative data on double digits for ages 11 and up.

Is the Musiek version or standard version better? Neither version is considered better. Both versions sell popularly and are widely used. Decisions are mainly based on which version the audiologist was originally trained in or by personal preference. Due to the similarities between the standard and Musiek versions, it is usually unnecessary to purchase both versions.

Time Compressed Sentence Test

The Time Compressed Sentence Test (TCST)* is for identifying and quantifying disorders of auditory processing in children specifically the child’s ability to understand acoustically distorted or rapid rates of speech.  In addition, results of testing with the TCST may yield insights into children with slow reaction times and speed of mental processing. It is considered a monaural low redundancy speech test (monaural separation closure -MSC) sensitive to brainstem and cortical lesions. The developer states the TCST can be administered and scored in less than 15 minutes.

The Time Compressed Sentence Test includes a) audio recording, and b) manual and score forms as printable pdf files. The extensive manual includes administration, scoring, and interpretation information. Age-specific normative data for ages 6, 7, 8, 9, and 10-11  is included. The developer recommends using the normative data for the 10-11 age category as a guideline for testing patients older than 11. Available from Auditec, Inc.  Call 1-800-669-9065 (from US) or 314-416-1050 (outside the US) to order. FREE shipping within the contiguous US.

Random Gap Detection Test – Standard & Expanded

The RGDT-Standard and Expanded version is an auditory processing disorder test for ages 5 and up using non-verbal stimuli. It is considered a temporal test using temporal resolution and is sensitive to cortical particularly left temporal lobe lesions.

The RGDT-Standard and Expanded includes the standard RGDT in its entirety along with an expanded portion at the end. The expanded portion of the test is included for individuals whose gap detection threshold exceeds 40 msec.  This test begins at time intervals longer than those measured by the standard portion of the RGDT, and includes time intervals of 10 msec. between 40 and 100 msec, and 50 msec. intervals between 100 and 300 msec.  The expanded portion of the test is administered in the same manner as the standard portion.

Individuals who require the expanded portion of the test have already demonstrated abnormal temporal processing abilities. The single purpose is to determine the time interval in which their gap detection thresholds exist. This information can be used to measure improvement in temporal processing abilities following remediation. By definition, patients with temporal processing disorders will have a wide range of gap detection thresholds. Therefore, there are no normative data associated with the expanded portion of the RGDT.

The Random Gap Detection Test-Standard and Expanded includes a) audio recording, and b) manual and score forms as printable pdf files. The 31-page manual pertains to the standard portion of the test. It is comprised of sections on development, background, administration, and interpretation. It includes normative data for ages 5 and up. An additional sheet with sections on administration and interpretation is included for the expanded portion of the test.

Random Gap Detection Test (RGDT) – Standard

The Random Gap Detection Test-Standard (RGDT) is an auditory processing disorder test for ages 5 and up using non-verbal stimuli. It is considered a temporal test using temporal resolution and is sensitive to cortical particularly left temporal lobe lesions.

This test is a variation on the AFT-R.  It differs from the AFT-R:  First, in the AFT-R, the stimulus presentations are in serial order from no gap to large gap and back to no gap, often resulting in perseveration in some subjects.  Since randomization successfully eliminates the problem of perseveration, the RGDT gap duration presentations of the stimuli are randomized.  Second, the number of test frequencies has been reduced to four.  Third, Click stimuli have been added. The developer states it takes approximately 10 minutes to administer and score the RGDT.

The Random Gap Detection Test-Standard (RGDT) includes a) audio recording, and b) manual and score forms as printable pdf files. The 31-page manual is comprised of sections on development, background, administration, and interpretation. It includes normative data for ages 5-7, 8, 9, and 10-11. The developer recommends using the normative data for the 10-11 age category as a guideline for testing patients older than 11. (Normative values for the AFT-R are included for ages 5-70 due to their similarity.) Available from Auditec, Inc.  Call 1-800-669-9065 (from US) or 314-416-1050 (outside the US) to order.
